got a stock 92 Lude Si. new h23 motor only has around 40k on it. i'm only looking for around 200 to 220 hp range, so i'm not asking for much from either engines ( or head swap) but i also dont want to have my car at a shop for a couple weeks. i hope to do the work myself, but since i dont know shit about turbos, i'd havta do my studying up, and also will the h23 hold up to 6-7 psi without doing internals, and how much gain will i get from the turbo application. thanx to anyone who responds. Dan ps. if you want to, just vote, so atleast i get an overall opinion. pss. plus i dont want to spend a fortune, maybe like 3k tops.
